Switching to a deep-cycle battery whether for camping, backup, or RV always has its perks. These batteries are famous for being the standard not only because of their lifespan but because of their ability to supply power for an extended period of time. They work well even at an 80% discharge level, making them ideal for off-grid camping and even for marine applications.
Aside from their superior quality, deep-cycle batteries are also known to be expensive, particularly lithium deep-cycle batteries. While you always have the option to go for cheap deep-cycle batteries like lead-acid or AGM, these won’t really give you good value for your money, especially if you’re an avid camper. LiFEPO4 deep-cycle batteries cost $500 to $3,000 depending on the size, model, and brand of the battery pack. The upfront cost may be high, but these batteries last for 7 to 10 years—definitely, a good deal if you think about it. Conventional batteries usually retail below $500, and may even go as low as $100 but in terms of performance, longevity, and user safety, they are usually lagging behind lithium batteries.
Are Deep-Cycle Batteries Worth It?
This depends on where you will use your deep-cycle batteries. Since they are designed to supply steady power for a longer timeframe, they'll be worth every penny if you camp out a lot or go on road trips often. Also, if you live in an area prone to power outages and are in need of a reliable battery backup, this would be a good investment as well. Every battery bank—whether it's a lead-acid deep-cycle battery, AGM deep-cycle battery, or even lithium battery—tends to go bad if you keep it unused for some time. If you plan to use yours occasionally, better opt for another battery type or power source instead, like inverter generators.
Are Cheap Deep-Cycle Batteries Good?
Generally, the rule when buying deep-cycle batteries is that the cheapest ones are usually not the best. It's better to invest in a good quality power pack that works well even as a heavy-duty battery than get a cheaper one and replace it from time to time. However, if you want to scale down or save a bit, there are discount batteries available that are of excellent grade too. Here at Outbax, we have a variety of deep-cycle batteries for sale.

How To Maintain Deep-Cycle Batteries?
Keeping your deep-cycle batteries in good shape is easier than you think. The key to this is regular monitoring. First, always keep your batteries fully charged, with a voltage of 12.5V and above. Constantly charging it partially may cause irreversible damage and affect your battery life too. You can use a voltmeter for easy tracking, and make sure to charge right away after you have returned from your trip.
You might think your only concern is the battery pack itself. This is not true. Every inch of your battery should be inspected frequently, from its terminals, screws, clamps, and cables. If you're using maintainable batteries, make it a habit to check its electrolyte level and top it up with distilled water only. You can also apply a thin layer of oil to your terminals to avoid corrosion. Lastly, most deep-cycle battery issues spring from improper charging. The best way to recharge should always be through a multi-stage battery charger and before you plug it in your battery, make sure both of their voltage match. Do it in a well-ventilated area and away from open flames for your safety as well. Most importantly, follow the manufacturer's instructions to avoid overheating, which can also cause the battery to explode.
